createTorusMesh can now create a partial torus

Browse Source 
Capping the torus also supported.
Bit arguably if caps belong in this function, but default for caps is off and they can be useful.
(one could also code partial minor circles ... but I'm stopping there)

//! Create a torus mesh
/** Note: Segments might get reduced to ensure it fits into 16-bit meshbuffer.
With 255 segments for minor and major circle you'll hit the maximum.
When using caps 2 more vertices are added.
Note: UV's for caps are probably not useful
\param majorRadius Starting from mesh center
\param minorRadius Starting from a circle at majorRadius distance around center
\param majorSegments Segments for major circle. Will use at least 3 segments.
\param minorSegments Segments for minor circle. Will use at least 3 segments.
\param angleStart Start major circle between 0 and 360<36> and < angleEnd
\param angleEnd End major circle between 0 and 360<36> and > angleStart
\param capEnds When you don't create a full major circle you might want caps
0 = no caps (default)
Bit 1: add cap at angleStart
Bit 2: add cap at angleEnd
